Background Dermoscopy provides additional criteria for the diagnosis of skin lesions. Objective To investigate the dermoscopic aspect of clear cell acanthoma (CCA). Methods Six consecutive cases of CCAs were observed under conventional dermoscopy (Case 1–4) or videodermoscopy (Case 5–6). Results Common dermoscopic findings were: (i) squamous surface with translucid collarette; (ii) dilated capillary loops, mainly perpendicularly orientated to the skin surface, as dotted, pinpoint‐like structures, regularly distributed in a reticular array over the surface. Conclusions The vascular psoriasis‐like dermoscopic findings seem to be a clue for CCA and provide evidence of an inflammatory process for CCA formation.
